Title
(EN) A BALL VALVE AND ACTUATOR FOR OPERATING VALVES AND THE LIKE
(FR) VANNE A BOISSEAU SPHERIQUE ET ACTUATEUR DE COMMANDE DE VANNES ET ANALOGUE
Abstract
(EN)
In one aspect the invention relates to a ball valve of the type comprising a ball member (83, 85) provided with two axially displaceable sleeves (66A, 66B) adapted to be displaced outwards to sealing engagement against seats provided in the surrounding valve housing (76) in the open position of the valve, so as to form a flow passage (73) through the valve, and which comprises a hollow drive axle for the rotary movement of the ball member between open and closed position and a drive spindle (12, 69) through the hollow drive axle, adapted to bringing about the axial displacement movement of the sleeves. On the drive spindle (69) and for rotation together with it there are provided two preferably disc shaped, first cam members (68A, 68B) on either side of the sleeves (66A, 66B) and the sleeves are provided with corresponding and cooperating second cam members (67A, 67B) for the axial displacement by rotation of the drive spindle (69) in relation to the ball member (83, 85). As a second aspect there is also described an actuator for operating valves and the like, in particular a ball valve as above, comprising a hollow output drive axle (32) and an output drive spindle (12) extended through the hollow drive axle, in order thereby to make possible two different operational movements by rotation of the drive axle (32) and the drive spindle (12), respectively. The ball valve and the actuator have particularly interesting uses in oil related industry and on oil rigs or the like.
(FR)
Dans un aspect, l'invention concerne une vanne à boisseau sphérique du type comprenant un boisseau (83, 85) doté de deux manchons (66A, 66B) mobiles axialement, adaptés pour être déplacés vers l'extérieur en contact étanche contre des sièges prévus dans le logement (76) de vanne circonvoisin, dans la position ouverte de ladite vanne, de manière à former un passage d'écoulement (73) à travers cette dernière, et comprenant un axe d'entraînement creux permettant le mouvement rotatif dudit boisseau sphérique entre les positions ouverte et fermée, ainsi qu'une tige d'entraînement (12, 69) passant dans l'axe d'entraînement creux, adaptée pour déclencher le mouvement de déplacement axial des manchons. On a prévu sur la tige d'entraînement (69) deux premières cames (68A, 68B) de préférence en forme de disque tournant avec ladite tige, sur les deux côtés des manchons (66A, 66B), ces derniers étant dotés de secondes cames (67A, 67B) correspondantes et coopérantes pour permettre le déplacement axial par rotation des tiges d'entraînement (69) par rapport au boisseau (83, 85). Dans un second aspect, l'invention prévoit également un actuateur destiné à commander les vannes et analogue, notamment une vanne à boisseau telle que précitée, comprenant un axe d'entraînement de sortie creux (32), ainsi qu'une tige d'entraînement de sortie (12) s'étendant dans ledit axe d'entraînement creux, afin de permettre deux mouvements opérationnels différents par rotation de l'axe d'entraînement (32) et de la tige d'entraînement (12), respectivement. Ladite vanne à boisseau sphérique et l'actuateur trouvent des applications particulièrement intéressantes dans l'industrie pétrolière ainsi que sur des plateformes de forage et analogue.
